VALVE.

Application filed October 18, 1922; Serial No. 595,408.

To all whom it may concern Be it known that I, .ARTl-IUR H. B; GORE, acitizen of the United States, and a resident of Maricopa, in, the countyof Kern and State of California, have invented new and usefulImprovements in Valves, of which the following is a specification.

This invention relatesin general to valves, and more particularly avalve or nozzle adapted to be employed when filling receptacles withfluids. Theniain object of my invention is to provide an improved valve,ornozzle for theabove purpose and particularly applicable to oil tanksand tank cars whereby the oil, or other liquid with which the tanks are;filled, may be supplied from a suitable source to the tanks in a uniformvolume, and automatically operable when a predetermined level of thefluid in the tanksisreached forpositively shutting oil thefurther-supply of fluid to the tanks,

thus eliminating waste oi the fluid, loss of time and greatinconvenience which 15 gen-- erally attendant upon-the filling or suchtanks with-methods now in vogue.

It is also an ob ect,of lilllS invention to provide afilling nozzle forfluldreceptacles adaptable for use with any kindo'f fluid, and

embodying an integral body with an automatically operable-shut-otf valvetherem and a float controlled operating member c0nnected with a floatadapted to be suspended into the receiving tank, for operating theshut-off valve when a proper or maximum level of the fluid is attainedinthe tank-s. Still other objects may appear as the descriptionprogresses.

I have illustrated one practical embodiment of my invention in theaccompanying drawings, subject to modification within the scope of theappended claims without departing from thespirit thereof.

In said drawings:

Fig. 1 isa sectional elevation of my improved filling nozzle.

Fig. El is a top plan view of the same.

Fig. 3 is asectional plan on line 33 of F in. 1.

Fig. 4-. is a side elevationas viewed from the right hand side of Fig.1.

Fig. 5 is abottom plan of the nozzle, partially broken away.

In a preferred form, such as shown: in the drawings, B represents anintegral body structure partaking substantially of thenature of astandard pipe fitting and having an inletportion I and an outlet portion0 longitudinally alined on the body. Inlet 1 may be externally threaded,as shown, to receive a section of pipe P, by means of which the fluidmay be conveyed from; a source of supply to the nozzle. Outlet O mayalso be externally threaded so as to receive a short section of pipeconstituting, a disclnurge nozzle N which is adapted to be suspendedwithin the inlet. of a receptacle or tank as at R.

Body B has a. longitudinal passage P extending therethrough foraffording communication between the pipe P and nozzle N, so that whenthe valve is open the fluid may flow uninterruptedly therethrough.

An extension E is provided on one side of body B and has a lower archedwall and an outer curved wall W with an internal chamber Bformed.therebetween for loosely receiving and supporting a ball valve Vwhen the valve is open The arrangement of walls W and W are such thatthe valve V will seat on the outer portion ofthe arch-ed wall W over thevertical center line of the curve of said wall, and will be thus held'inposition against-the outer portion of wall N, as shown in 1, by gravity.

An extension E, is provided integral with .and projecting downwardlyfrom, the extension E and has a sen'ii-spherical recess Scon'nnunlcatlng wlth the chamber B which is adapted to receive and holda ball operating member 2) slidably mounted in a roduced end. portion eby means of a valve stem V Said valve stem has a valve V of the poppettype thereon below'the end of portion (2 and said portion is bored toreceive the stem V as shown. Portion eis threaded to receive a valve capC, the'end of which abuts a shoulder on the lower end of extension E andsaid cap serves to enclose'the valve V.

A valve seat h is provided in the lower end of the cap C and is tapered,or beveled to iorrespond to the bevel of the valve, whilethe lowerportion V of the valve stem projects through the end of the cap an'd'isattached at its lower end to a ball float F, hollow as shown, and oilight weight. Cap C is threaded on the end oi? extension 131' by meansof a wrench applied thereto, and the stemis of a properlength to suspendthe float into the receptacle it and below the maximum fluid levelthereof.

Ball valve V is adapted to seat in a correspondingly formed valve seat Sformed internally of the outlet 0 so as to positively shut off thesupply of fluid from the tank or receptacle B when a proper level isattained.

The operation is as follows:

The nozzle being first properly attached to the pipe P and a source ofsupply, is suitably held in position over the inlet of the tank R- withthe nozzle N thereof projecting downwardly into the tans. The ball valveV is then raised into the position shown in Fig. 1 for holding the valveopen and the fluid may be pumped or supplied by gravity to' the tankuntil a maximum level with the tank is attained, whereupon the float Fwill be elevated, the valve V opened and the ball operating member Z;will be thrustupwardly against the lower and outerportion of theperiphery of ball valve V, and said valve will be moved over the archedwall W and will automatically fall downwardly into the passage P andseat in the valve seat S. Thus, the supply of fluid will beautomatically shut off, and immediately upon the closing of the valve Vthe pressure in the passage P and chamber B will be exerted against theball member 6 and upper side of valve V, thus forcing the float lldownwardly into the fluid within the tank It, and closing valve Vagainst the leakage of the fluid therethrough.

It will be noted from the foregoing description that the valves V and Vco-operate with each other for positively and com-' plcte ly shuttingot'f the supply of the fluid to the tank ll when the proper level isattained. (Ether tanks may he tilled, one after the other in a similarmanner and the level of the fluid in tank R is determined by the depthof the float F in the tank, and the elevation of the entire structurethereabove.
